Safety Information and Precautions
This guide is packaged together with the product� It contains basic information for quick start of the drive� For safety and more
information, please refer to IS580 Servo Drive Advanced User Guide, which can be Downloaded on website: http://www�inovance�cn�
■
Electrical Safety
Extreme care must be taken at all times when working with the servo drive or within the area of the servo drive� The voltages used in
the servo drive can cause severe electrical shock or burns and is potentially lethal. Only authorized and qualified personnel should be
allowed to work on servo drives�
■
Machine/System Design and Safety of Personnel
Machine/system design, installation, commissioning startups and maintenance must be carried out by personnel who have the necessary
training and experience� They must read this safety information and the contents of this manual� If incorrectly installed, the servo drive
may present a safety hazard�
The servo drive uses high voltages and currents (including DC), carries a high level of stored electrical energy in the DC bus capacitors
even after power OFF� These high voltages are potentially lethal�
The servo drive is NOT intended to be used for safety related applications/functions� The electronic “STOP & START” control circuits
within the servo drive must not be relied upon for the safety of personnel� Such control circuits do not isolate mains power voltages from
the output of the servo drive� The mains power supply must be disconnected by an electrical safety isolation device before accessing the
internal parts of the servo drive�
Safety risk assessments of the machine or process system which uses an servo drive must be undertaken by the user and or by their
systems integrator/designer� In particular the safety assessment/design must take into consideration the consequences of the servo
drive failing or tripping out during normal operation and whether this leads to a safe stop position without damaging machine, adjacent
equipment and machine operators/users� This responsibility lies with the user or their machine/process system integrator�
System integrator/designer must ensure the complete system is safe and designed according to the relevant safety standards� Inovance
Technology and Authorized Distributors can provide recommendations related to the servo drive to ensure long term safe operation�
The installer of the AC Drive is responsible for complying with all relevant regulations for wiring, circuit fuse protection, earthing, accident
prevention and electromagnetic (EMC regulations). In particular fault discrimination for preventing fire risk and solid earthing practices
must be adhered to for electrical safety (also for good EMC practice)� Within the European Union, all machinery in which this product is
used must comply with required directives�
■
Electrical Installation - Safety
Electrical shock risk is always present within an servo drive including the output cable leading to the motor terminals� Where dynamic
brake resistors are fitted external to the servo drive, care must be taken with regards to live contact with the brake resistors, terminals
which are at high DC voltage and potentially lethal� Cables from the servo drive to the dynamic brake resistors should be double
insulated as DC voltages are typically 600 to 700 VDC�
Mains power supply isolation switch should be fitted to the servo drive. The mains power supply must be disconnected via the isolation
switch before any cover of the servo drive can be removed or before any servicing work is undertaken stored charge in the DC bus
capacitors of the PWM inverter is potentially lethal after the AC supply has been disconnected� The AC supply must be isolated at least
10 minutes before any work can be undertaken as the stored charge will have been discharged through the internal bleed resistor fitted
across the DC bus capacitors�
Whenever possible, it is good practice to check DC bus voltage with a VDC meter before accessing the inverter bridge� Where the servo
drive input is connected to the mains supply with a plug and socket, then upon disconnecting the plug and socket, be aware that the plug
pins may be exposed and internally connected to DC bus capacitors (via the internal bridge rectifier in reversed bias). Wait 10 minutes to
allow stored charge in the DC bus capacitors to be dissipated by the bleed resistors before commencing work on the servo drive�
